Bio-physical interactions of small pelagic fish schools and zooplankton prey in the California Current System over multiple scales

Creator:

Kaltenberg, Amanda May

Abstract:

Small pelagic fish represent a critical trophic link between plankton and large predators in marine upwelling ecosystems such as the California Current System. Populations of these fish are highly variable over time and are characterized by extreme fluctuations in abundance, which have significant ecosystem impacts. The causes driving this instability...

Distribution, structure, and function of marine ecological communities in the northern California Current upwelling ecosystem

Creator:

Reese, Douglas Charles

Abstract:

Within systems characterized by substantial spatial and temporal variability, abundances of organisms tend to be higher in localized areas. Within the northern California Current system, the identification of such marine, biological hotspots would be of great importance to resource managers, conservationists, and research planners, and is consequently a growing area...

Trophic dynamics of marine nekton and zooplankton in the Northern California Current ecosystem

Creator:

Miller, Todd William

Abstract:

The Northern California Current (NCC) ecosystem exhibits extreme seasonal, interannual and interdecadal shifts in the abiotic environment and shifts in primary and higher production. This variability is also apparent in the spatial structure of the ecosystem with nearshore-shelf waters (<150 m isobath) being highly productive and having a different community...
